A method for producing a double jersey fabric on a double jersey, single jacquard circular knitting machine includes steps of knitting a front side of the fabric on a cylinder (C) and knitting the rear side of the fabric on a dial (D) of the machine, knitting a base yarn on a rear side of the fabric, except for connecting points where the base yarn is knitted on the front side of the fabric. The method additionally includes steps of inserting a pattern yarn before a start of a pattern unit, which is produced using the pattern yarn, knitting the pattern yarn on the front side of the fabric in the pattern unit and cutting off the pattern yarn after the pattern unit.

A footing for circular knitting machines for hosiery, comprising a supporting structure that comprises: uprights that are extended along substantially vertical directions; at least one tubular reinforcement element, which is connected rigidly to the uprights and mutually connects the uprights.

A knitting method and an apparatus for a cylindrical biaxial weft-knitted three-dimensional knitted structure. The biaxial three-dimensional knitted structure comprises two weft plain stitch structures (7, 7′), a group of spacer yarns (416), two groups of weft inserting yarns (415, 415′) and a group of warp inserting yarns (43), wherein the two groups of weft inserting yarns are used for selective weft inserting on a needle dial (11) or a needle cylinder (13), the warp inserting yarns are positioned between the two groups of weft inserting yarns, the two weft plain stitch structures are connected with each other by the group of spacer yarns, for jointly clamping the weft inserting yarns and the warp inserting yarns, in order to form a biaxial weft-knitted three-dimensional knitted structure. Such three-dimensional knitted structure improves the mechanical properties of three-dimensional knitted fabrics; by increasing the interval between the needle dial and the needle cylinder, the thickness of the knitted structure is increased, which is suitable for the reinforced structure of high-performance structural and functional composite materials, and expand the field of the use of the knitted structures.

A circular knitting machine with a needle cylinder (11), in which cylinder needles (13) are mounted to be longitudinally displaceable, and a dial (12), in which rib dial needles (14) are mounted to be radially displaceable, wherein auxiliary elements (15), in particular sinkers, associated with the cylinder needles (13) and auxiliary elements (16), in particular sinkers, associated with the rib dial needles (14), as well as separate thread feeds to the cylinder needles (13) and to the rib dial needles (16) are provided, wherein separate tubular knits (19, 20) can be produced simultaneously or one after the other with the cylinder needles (13) and with the rib dial needles (14).

An electronic yarn changing device for a circular knitting machine includes at least two driving units, at least two impelling plates respectively connected to the driving units, and at least two yarn feeding units. The impelling plates are impelled by the respective connected driving units to perform a one-dimensional motion. The yarn feeding units are arranged side by side, and are each provided sequentially with a yarn feeding plate, a yarn clamping plate, a mobile blade plate and a fixed blade plate. The yarn clamping plate includes a plurality of guide columns disposed correspondingly to the yarn feeding plate. The yarn feeding plates are respectively pushed by the corresponding impelling plates to perform a two-dimensional motion due to the plurality of guide columns. The mobile blade plates are also respectively pushed when the corresponding impelling plates perform the one-dimensional motion, and individually perform a one-dimensional motion once being pushed.
